The specific embodiment
Below in conjunction with accompanying drawing and by embodiment, the present invention is described in further detail, and following examples are explanation of the invention and the present invention is not limited to following examples.
Referring to Fig. 1-Fig. 7, the present invention mainly comprises support frame I, base 1, column 2, upper beam 3, moving beam 4, lift cylinder 5, guide post 6, air motor 7, inductance type switch 8, unscrews spanner 9 and case card bolt 10.
The support frame I comprises base 1, column 2 and upper beam 3, base 1, column 2 and upper beam 3 are connected mutually, column 2 is between base 1 and upper beam 3, column 2 is installed on base 1, be fixed with upper beam 3 on column 2, the support frame I works the effect of being fixedly connected with, and guarantees carrying out during case card bolt 10 unscrews process, and whole device is firm.
Spanner 95 comprises round platform 951 and bayonet lock 952, and described round platform 951 bottom surfaces evenly are provided with four bayonet locks 952, and described round platform 951 upper surfaces have circular hole 953, and this circular hole 953 mates mutually with described sleeve pipe 93.
With reference to Fig. 1-Fig. 3, the moving beam 4 be connected with lift cylinder 5 remains on a high position, and what with air motor 7, be connected unscrews spanner 9 in rotation status not, and case card bolt 10 is in locking state, and lift cylinder 5 drives moving beam 4 and moves downward.
Referring to Fig. 4-Fig. 5, the plan structure schematic diagram that Fig. 4 is case card bolt head, the A-A structural representation that Fig. 5 is Fig. 4, in order to make spanner 95 more easily insert the head 101 of case card bolt, spanner 95 is made into the structure be comprised of four bayonet locks 952, and the head 101 of case card bolt is made into the structure be complementary.
Referring to Fig. 6; in the time of in head 101 neutral gears of spanner 95 insertion case card bolts, lift cylinder 5 stop motions, and remain on low level; thereupon; air motor 7 drives and unscrews spanner 9 rotations, case card bolt 10 is applied and unscrews moment of torsion, when 10 rotations of case card bolt are risen; sleeve pipe 93 is along with rising together; now Compress Spring 92 is gradually reduced, and to offset the rigidity difference in height that rises and produce because of the bolt rotation, has effectively protected whole device not damaged.
Referring to Fig. 7, when inductance type switch 8 detects round boss 932 edge at sleeve pipe 93 middle parts, to PLC, send signal, mean that case card bolt 10 has unscrewed and put in place, air motor 7 stops operating.
During work, at first unscrew device in original state: the moving beam 4 be connected with lift cylinder 5 remains on a high position, and what with air motor 7, be connected unscrews spanner 9 in rotation status not.
When the transport trolley that is loaded with the swage sandbox be pushed to this device under the time, now case card bolt 10 is in locking state, lift cylinder 5 drives moving beam 4 and moves downward, guide post 6 plays the effect of lead and guaranteeing moving beam 4 steady declines in this process.
In the time of in head 101 neutral gears of spanner 95 insertion case card bolts, lift cylinder 5 stop motions, and remain on low level, then, air motor 7 drives and unscrews spanner 9 rotations, thereby case card bolt 10 is applied and unscrews moment of torsion, when 10 rotations of case card bolt are risen, sleeve pipe 93 rises thereupon together, and now Compress Spring 92 is gradually reduced, to offset the rigidity difference in height that rises and produce because of 10 rotations of case card bolt, effectively guaranteed to unscrew device not damaged.
When inductance type switch 8 detects round boss 932 edge at sleeve pipe 93 middle parts, send signal to PLC, mean that case card bolt 10 has unscrewed and put in place, air motor 7 stops operating immediately, thereupon, lift cylinder 5 drives moving beam 4 and rises to a high position, is back to original state, wait for entering of next transport trolley, complete the work that next time unscrews case card bolt 10.
In the present embodiment, motor output shaft 71 is connected for the cylinder plug-in type with the sleeve pipe 93 in unscrewing spanner 9, said " connection of cylinder plug-in type " refers to that motor output shaft 71 is column types, sleeve pipe 93 is made into circular port, the slightly larger in diameter of this circular port is in the diameter of motor output shaft 71, and motor output shaft 71 inserts in circular port, under the effect of external force, both just can insert and stretch out, and are the cylinder plug-in type and connect.
The quantity that unscrews device in the present embodiment is determined according to the quantity of the case card bolt 10 on transport trolley; the installation site of inductance type switch 8; distance from the bottom surface of moving beam 4; according to actual use procedure, adjusted; as long as the distance after installation; unscrewing while putting in place; round boss 932 can be in inductance type switch 8 position; can detect and put in place; PLC is sent to signal and get final product, to unscrewing device, carry out the simple change of connected mode, quantity and structure all in the protection domain of patent of the present invention.
In addition, it should be noted that, the specific embodiment described in this specification, the shape of its parts and components, institute's title of being named etc. can be different, and the above content described in this specification is only to structure example of the present invention explanation.Allly according to patent of the present invention, conceive equivalence variation or the simple change that described structure, feature and principle are done, be included in the protection domain of patent of the present invention.Those skilled in the art can make various modifications or supplement or adopt similar mode to substitute described specific embodiment; only otherwise depart from structure of the present invention or surmount this scope as defined in the claims, all should belong to protection scope of the present invention.
